Fixed displacement axial piston pump type K60N - Hidracomp

Fixed displacement axial piston pump type K60NMax. operating pressure p maxMax. geom. displacement V g= 400 bar (5500 psi)= 108 ccm/rev. (61 cu in)1.21. GeneralThe fixed displacement axial piston pump type K 60N (bent axis design) is especially suited for demanding, high-duty service.The pump covers the whole displacement range up to 108 cm 3 /rev. The pump has been developed with modern styling and designto satisfy market demand as to high flow performance, high pressures with high effciency and very small dimensions. The pump isavailable both to DIN and SAE standards and can be mounted either directly at the gear box or via a drive shaft. If necessary it canalso be augmented with a by-pass valve.The pumps have the following advantages:' High speed rating' Low noise level' Smooth running and long bearing life' External fluid leaks are eliminated by using O-rings at all sealing surfaces' Optional by-pass valve© 2001 by HAWE HydraulikHAWE HYDRAULIK SESTREITFELDSTR. 25 • 81673 MÜNCHEND 7960 KFixed displasmentaxial piston pumpMarch 2001-02

Flexible hoses should be fixed by two strong hose straps. Suction filter should not beassembled.All hydraulic lines should be flushed with appropriate hydraulic fluid before start-up. The pumpcase should then be bled via the uppermost drain port.Note: The surroundings should be clean while filling the pump. Check the rotation direction ofdrive and pump prior to initial operation.At start-up and during the first few minutes of the operation the pressure relief valve should beset to 50 bar (700 psi) or less.
